3 Claims.

This invention relates to devices for use in facilitating the transmission of fluid from one tank or compartment to another and for straining the fluid in its transmission. More particularly, the invention relates to devices of this type and kind designed for marine uses in the transmission of gasoline and similar iluids from tanks to the storage compartments of a vessel, and the object of the invention is to provide a device of the character described, employing a springseated control valve adapted to be automatically opened by the pressure of iluid introduced into the device in providing what might be termed a pressure actuated iilling cap; a further object being to provide means keying the valve as wel] as the valve supporting casing against movement or displacement utilizing a lock controlling said keying means, said keying means and lock being all arranged within the structure of the valve casing, and with these and other objects in view the invention consists in a device of the class and for the purpose specined, which 'is simple in construction, efficient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the follow- Y for marine uses where the same may be imbedded in the deck of a vessel or in the wall structure of a tank or compartment of the vessel, or on the other hand, incorporated in what is called va stand line or piping ofthe vessel. Further my improved cap is designed to be used where pressure of the fluid introduced through the cap serves to automatically open the valve of the cap, the valve being normally spring-seated. In devices of this type and kind I have also incorporated means for locking the valve in closed po- "sition while at the same time keying the valve supporting casing against displacement, thus preventing tampering with the lling device and ultimately with the iiuid controlled thereby.

In Fig. 1 of the drawing is shown one adaptation of the invention, and in this ligure IQ represents the casing of the device, the casing being substantially cup-shaped in form and is provided at the bottom thereof with a large discharge Il which is preferably threaded to receive a pipe or coupling in certain uses of the device, particularly in extending the device from a ships deck to a tank or compartment arranged below the deck surface. The upper end portion of the casing l is enlarged as seen atIZ, and terminates at its upper or outer end in a flange I3 seated in a groove I4 of a supporting wall or flooring l5 so that the upper surface it of the flange is flush with the upper surface Il of the support. Any suitable fastenings may be employed to secure the casing to the support. In the construction shown, screws I8 are employed to enter a Wooden support I5.

Where the casing IEB proper joins the enlargement I 2 the' casing has an inwardly protruding ring seat IQ upon which a valve-seat casing rests and to which the same is secured by al number of screws 2i, a gasket 22 being employed between the part it and the periphery of the valve casing 20.

The casing 2i) has an upwardly extending internally and externally threaded sleeve portion 23 which forms a large admission passage 24 through the casing 2t into the casing I0. On the base of the sleeve portion 23 is a beveled valve seat 25 upon which a valve 26 seats. The Vvalve 26 has a downwardly directed stem 2l which is freely supported in an open-work frame 28 having a top ring portion 29 which seats between the casing 2d and the part I9 ofthe casing I0, and centrally of thevlower portion of the frame is a bearing 3i! in Whichthe stem 2l is freely moved.

Between the bearing .i6 and the valve 26 is a coil spring 3l which is arranged around the stem 2l and serves to normally support the valve on the seat 25 to resist predetermined pressures while at the same time providing automatic opening of the valve in pressure injection of fluid into the admission passage 2li through a pipe or tube coupled with the sleeve 23 after a closureplate 32 has been removed. The plate 32 seats upon a l grooved portion 33 formed at the top of the casing I0 or in the ange portion I3 thereof, and

this seating of the plate is sealed by a gasket 34.

The plate 32 has a downwardly directed internally threaded sleeve portion 35 which engages .the external threads of the sleeve 23V. Thejplate plate 32 as will be apparent.

Arranged upon the skeleton frame 28 and supported by this frame in the casing I is a large employed. casing |i| is a casing 4`| which instead of having the downward discharge has a large discharge y 48 at one side of the casing which is flanged as `seen at 49 to be mounted on the flange 50 of a 1 stand line or piping 5|, a suitable gasket 52 being employed between the flanges 49 and 50 and bolts or screw devices 53 are employed to couple the ismade, nor is this structure described. ever in Fig. 2 part of the valve structure is indi- 1 cated in dotted lines merely to illustrate the general similarity in arrangement.

screen or strainer 31 which is substantially cupshaped in form and is disposed in spaced relation to the Walls of the chamber 38 formed within the bottom portion of the casing l0.

The casing 2|) in alinement with one of the screw receiving portions thereof is enlarged as seen at 38. This enlarged portion has a radial aperture 4!! in which is mounted a key rod 4|. The outer end portion of the rod 4| engages one side of the screw 2| to key this screw against rotation thus retaining the casing 20 against displacement from the casing I0. The outer end of the aperture 40 is plugged as seen at 42 in order to seal this aperture as will be apparent. The inner end of the rod 4| is provided with an aperture or eye 43 to receive an upwardly projecting pin 44 on the valve 26. The pin has above the rod 4| an aperture to receive a padlock or other lock element 45 which checks inward or opening movement of the valve 26 and also prevents displacement of the rod 4|.

It will be understood however, that in the use first removed, after which the lock 45 is removed by the use of a suitable key or otherwise. A pipe or coupling may then be connected with the sleeve 23 and fluid may be introduced under pressure into the chamber 24 unseating the valve 26 then passing out through the strainer 31 and into the chamber 38 and out through the discharge or a pipe or tube coupled therewith.

When it is desired to remove the casing 20 for cleaning or replacing the strainer 31 or for making any alterations, repairs or replacement of the parts, this can be accomplished by first removing the lock 45, then manually or otherwise depressing the valve 26 to disengage the pin 44 from the rod 4|, and then drawing the rod into the chamber 24 and removing the same through the open end of the chamber. This will free the casing 26 to permit its detachment by removing the screws 2| or where stud screws are employed, to

' simply remove the nuts 46 thereon.

l The structure shown in Fig. 2 of the drawing differs from the structure shown in Fig. 1 basically in the form and contour of the main casing In other words, substituted for the parts. The only other difference in the two structures would be in providing a smaller flange 54 at the top of the casing 41 simply large enough to provide the groove seat 33 as in Fig. 1, upon Which the closure plate 32 rests. In that the rest of the structure of Fig. 2 is identical with that shown in Fig. 1, no specic showing thereof How- It will be apparent that the cover or closure plate for the iilling device has its outer surface flush with the corresponding surface of the casing and when the casing is imbedded in a support the entire device presents a surface in common alinement with that of the support. It will also be apparent from a 'consideration of Fig. 1, that the closure plate serves to conceal the lock within the chamber 24 and further protect the lock from exposure to the elements.
